Java in-depth exploration 12-framework Integration

1.Spring and Hibernate integration

Hibernate and Bean.xml are required to be configured

1) Key points: sessionfactory create transaction to spring for springioc;session transaction processing

2) Jar Package:

　　　　Connection Pool / Database Driver Package

　　　　H ibernate related jars

　　　　Spring Core Pack (5 )

　　　　Spring AOP Package (4 )

　　　　Spring-orm-3.2.5.release.jar "Spring 's support for hibernate "

Spring-tx-3.2.5.release.jar "Transaction related"

3) Integration steps: A: Create a sessionfactory bean node; B: Add a transaction to the business method of the logical layer

A:sessionfactory three ways to integrate in spring beans:

1. All hibernate.cfg.xml introduced into the Bean.xml

2. Partial Introduction: DataSource connection pool written in spring

3. Write all in Bean.xml

B: Add transactions to the logical layer using AOP Transaction mode

4) Example:
